Heating/Cooling
request
objects
The
setting
“Heating/Cooling
request
enabled”
can
show
objects,
which
indicates
a
beginning
heating
or
cooling
process.
So
these
objects
are
status
objects.
The
objects
can
be
used
for
the
visualization
of
a
beginning
or
ending
heating/cooling
process.
So,
for
example,
a
red
LED
could
show
a
heating
process
and
a
blue
LED
a
cooling
process.
A
further
opportunity
for
the
usage
is
the
central
switch
of
a
heating
or
cooling
process.
So
can
be
realized
that
all
heating
devices
of
a
building
switch
on,
when
a
controller
gives
out
a
heating
request.
The
1
Bit
communication
object
gives
as
long
a
1
‐
signal
out
as
the
process
is
active.

following
